Flexible hose, which should be discarded. Master OK
We will understand what quality hose differs from the bad, which meant his own shortcomings and even dangerous for the hosts, and for their neighbors. And in the end there is a short video on the topic. However, you can learn what to do if cistern water tight.
Doubtful complete hose
Normally with any mixer comes complete hose Dina 30-40 cm, which many of us feel free to put on the plumbing and do not suspect that this little "bomb". Most likely it will jerk and in some cases have to wait is not long. For the sake of truth, I note that this applies primarily to products with Chinese roots.
In the picture above that the foreground is seen a good hose, and behind him - a bad one. Mediocre sample comes with a mixer or a crane and suitable rather for a temporary, rather than permanent use. It can be distinguished by the absence of colored stripes on the shield, and it is made of aluminum or galvanized steel.
Blue and red colored stripes on the shield indicate that the product is designed for cold and hot water, respectively. On to the universal hoses are strips of both colors.
The very fragile braided hose, though metal, but it is thinner wires and inferior in strength, so it is faster prorzhaveet in a humid environment, which will lead to a breakthrough of rubber hose, which inside. This can happen in six months or a year after installation.
The end of the hose, the so-called nipples, too, are slightly different. The improved version of the product seals on two nipples, and on low hose only one that reduces its reliability.
For objectivity emphasize that a number of brand-name hoses, too, is one O-ring on nipple, causing their quality does not suffer, but this is not the liner inexpensive mixers.
Nuts both hoses that in the photo, complaints do not have, as the quality of the rubber pads on them. It happens that the hose is equipped with a questionable not rubber, and transparent silicone gasket, which is also good.
Quality rolling braid in a more expensive product is better, so it can withstand high water pressure load, and the second braided hose can twist even during the installation, when the nut is tightened key.
The service life of reinforced hose 5-10 years, the trial - 1 year or less. Wait until any of the hoses flow should not be, but if coming to the end of its life, defined by the system pressure and environmental conditions, it is better to replace. Both you and the neighbors will be calmer.
Here we describe only my experience that is sure to be supplemented.
